1.1 Getting started
1.1.1 What you need
You’ll need on your machine

  1. A JavaScript interpreter which provides a command line an editor on your machine. You’ll also able to download and unzip the course work folder.
    1.1.2 Windows and Linux
    For Windows the easiest thing to do is to download the JSDB interpreter, and use notepad (or some other editor).
    For Linux you and install Rhino and use your favourite editor.
    $ sudo apt-get install rhino
    1.1.3 Are you ready?
    You’ll want to be able to run the JavaScript interpreter from the command line when in the work folder. This will be
    automatic (via the PATH) with Linux and Rhino. For Windows the easiest thing to do is to place the jsdb.exe file in
    the work folder.
    When you’re ready type js at a command prompt. This starts the interpreter and gives you a js> prompt. You’ll get
    something like this.
    core-javascript-work$ js
    Rhino 1.7 release 2 2010 01 20
